 159 presidential scholars voted him the worst president in the history of the United States of America. Trump gave it back. The whole world is blowing up under him. They sparred over foreign policy, abortion, the economy, immigration. Asked if he'd accept the results of the November election, unlike four years ago, Trump equivocated. If it's a fair and legal and good election, absolutely. The president doubts it. Because you're such a whiner.
